'ments in radiators and Amore especially to those of the type adapted for use upon automobiles for cooling the circulating water for the engine. The primary objects of the invention are to provide a radiator which is so constructed in units that any damaged or defective part of the radiator may be easily and -quickly removed'and replaced Without requiring dismantling ofthe radiator; to provide a radiator ofthisV Yclass wherein the water cooling units are yieldingly connected to arigid outer member Hwhereby the vibrations and strains to which such 'radiators are subjected in service will not cause injury tov or leakage of these units;

and to provide a radiator composed of'units or sections of standard size whereby replacement of any unit or section may be accomplished easily -by unskilled persons and radiators of d iiierent sizes and capacities may be made by assemblingdiierent numbers of units or sections. b

To these vand other ends, the invention consists in certain improvements, and combinations and arrangementsof parts, all as will be hereinafter. more fully described, the novel features beingpointedout particularly in the claims at' thev end' oit the speciication. y

eially to radiators of the type adapted for use upon automobiles, and the preferred embodiment of the invention is shown in the accompanying drawings and will be hereinafter described in detail. It is to be understood that the invention is not restricted to the precise construction shown as equivalent constructions are contemplated and will be included within the scope ofthe claims. In the present instance, the radiator is composed of a relatively rigid outer member and a suitable number of cooling units or sections which are removably and flexibly mounted within the rigid outer member. inthe present instance, the rigid outer member comprises an upper water reservoir 1 which may be provided with the usual con- A nection to receive the heated water from the cooling jacket of the engine, a lower 'reser- Voir 2 which may beV provided with the usual outlet connection from the radiator to the engine water jacket, and a pair of side members 3. The upper and lower reservoirs are ofrigid .construction or the like, and the connecting side members BteXtend between and rigidly lspace the up- As shown, screws 4 and may extend through the outer ends ofthe upper and lower reseivoirs respectively and in to the upper and lower ends of the side'members 3 and serve to detachably unite these parts.

4 For example,4 lthey maybe cast of metal such as cast iron The bottom wall 6.

'of the upper reservoir is provided with holes 7, thev number of which depends upon Athe number of cooling units or sections to be used, and these holes are internally threaded.- The upper wall 8 of the lower reservoir is. provided with a similar number of holes 9,- but these holes -areunthreaded The cooling units or sections are arranged vertically and placed between the lower wall 6 of the upper reservoir and the upper wall 8 of the lower reservoir. These units are a size which may be adopted as a standard. Each unit comprisesupper and lower heads 10 and 11, a suitable number of water tubes 412 extending between the heads and having their ends fitted into the respective heads, and side plates 13 and 14; may be connected to and extended between the heads 10 and il to provide means for rigidly connecting and spacing them, Caps 15 and 16 are fitted preferably of duplicate construction and of .er the heads 10 and 11, thus providing water chambers at the upper and lower ends of the tubes whereby water may enterA the upper ends of the tubes and after flowing therethrough may discharge from the lower ends thereof. The cap '15 is provided with to fit into one of thethreaded holes 7 in the lower wall 6 of the lupper reservoir 1, and each nipple has a flange 21A on its lower 'end. A lock nut 22 'is also provided for each nipple 20, it being threaded thereon.

\ of the wall 8 of the lower reservoir.

In assembling a radiator of the construction just described, each section or unit is placed in position by inserting the nipple 18 on its lower end into the appropriate hole-,9 in the upper wall 8 of the lower reser- Voir, a washer or gasket 23 of rubber, leather vorother yielding material being` first placed `upon the nipple 18 whereby this washer or gasket will occupy a position between the lower wall of the cap 16 and the upper rsl-ige e nipple 2O is then screwed upwardly into the wall 6 of the upper reservoir to its full extent', and after the nipple 17 on the upper end of the unit is' brought. into line with the nipple 20 and a washeror gasket 24 of rubber, leather or other` yleldinngvmaterial has been placed in position around the nipple 17, the nipple 20 isjturned a direction to lower it, thereby bringing its flange 21 down upon the washer or gasket 24. The pressure exerted upon the upper end of the unit lby the nipple 2Q is sufiicient to compress the washers or gaskets 23 and 21 to an extent sufficient to insure water-tight joints at these points.

Furthermore, in order to prevent leakage of water along the thread of the nipple 20, a washeror gasket 25 of rubber, leather or vother suitable material may be placed between the lower side of the wall 6 of the upper reservoir and the lock nut 22, and by tightening the lock nut 22, the washer or gasket 25 is compressed sufficiently to produce a water-tight joint at this point, and

' unscrewing of the nipple 20 by vibration is prevented.

The cooling portion of the radiator is composed of an appropriate number of units or sections, each of duplicate construction, and these sections or units are flexibly connected to the rigid outer member. In consc- -quence, vibrations or strains. to Which the outer member is subjected will not affect the inner cooling sections, as the shocks are absorbed by the yieldable joints, and development of leaks is avoided. Each of these units or sections may be inserted and removed without in any way disturbing the adjacent section' or sections or the general structure of the radiator. Should a section or unit be injured or develo a leak, such section can be easily and quickly removed and another section or unit substituted, or if another is not available, thedefective or injured section or unitmay be removed and the holes 7 and 9 may be closed by corks` or other suitable plugs.

Preferably, a face plate 26 is provided to cover the fittings which connect the upper ends of the units or sections to the upper reservoir. If such plate is used, it will be removably secured in place in order to afford access to the fittings when it is necessary to remove a unit forrepair or replacement. Lugs 27 may be provided on the ends of the' lower reservoir to attach the radiator to the frame of the automobile. 90'

Aradiator embodying the present invention enables repairs to be made on the road or elsewhere without the -necessity of removing the radiator from the machine, it being necessary only to remove the defective. section and replace it by a new one which can be kept on hand, or the defective section can be removed and the holes therefor plugged with corks or the like. Furthermore, by using units or sectionsof standard 100 size, radiators lof different sizes or capacities may be built and the units or sections thereof will be interchangeable with the units or sections of other radiators.

I claim as my invention l 1. In a radiator, the combination of upper and lower rigid reservoirs, the bottom wall ofthe upper reservoir havingthreaded oplen'- ings therein and the top wall of the remaining reservoir having similar openings with- 110 out threads, a. set of vertical cooling sections each having nipples at their upper and lower ends with exterior surfaces tapering to the free ends of the nipples, the lower nipples loosely and detachably engaging the open- 115 ings of the Alower reservoirs, cylindrical nipples secured in the screw-threaded openings of the upper reservoir and into which the nipples at the upper ends of the sections extend, each of the sections being movable 120 vlonf 'jitudinally between said reservoirs and independently removable relatively to the other sections, and yielding gaskets interposed between the nipples to provide tight joints.

2. In a radiator, the combination of upper and lower reservoirs, the lower wall of the upper reservoir and the upper wall of the lower reservoir having corresponding openings therein, a, plurality of cooling sections 130 adapted to occupy the space between the reservoirs, each section having exteriorly tapered nipples projecting` from the center' of its upper and lower ends, the nipples on the lower end of the section frictionally and removably tting in the respective opening in tlie lower reservoir, and a cylindrical nipple for each section adjustably threaded said cylindrical nipple being operative to produce and maintain compression between the upper and lower ends of the section and l5 the respective reservoirs.

In testimony whereof have hereunto set niy hand in presence of two subscribing witnesses.
